lClaim.

. 1 This invention relatesto a device for removing dust, and more particularly to such a device adapted for use in excavating, mining'and similar work.

The primary object of this invention is the provision of an improved dust removing device acting on the principle of a suction fan and particularly adapted'to be utilized in removing dust such as is raised by drilling with ajackhammer or the like in mines, quarries, and similar places.

An additional important object of this invention is the provision of such a device which, by virtue of its dust removal will improve and errhance the health of the operator of the jack hammer or similar power drills.

'As conducive to a clearer understanding-of-this invention, it may here be pointed out that in such work as rock drilling, coal mining, and the like, .particularly in confined spacessu'ch as mines or other underground installations, the dust occasioned by rock drilling or coal drilling, or the like, frequently occasions, through inhalation into the lungs of the workers a very serious disease known as silicosis, It has been determined that this disease is occasioned solely by the action of the dust particles on the lungs of the worker, and accordingly in the absence of such dust particles, or in the reduction of the quantity thereof, the incidence of the disease would materially decline. A very important object of this invention, therefore, is the provision of a device adapted to be utilized in mines or the like whereby the dust occasioned by such drilling operation is removed at the source and conveyed to a convenient receptacle, thus preventing its permeating the air, and reducing the incidence of silicosis among the workers.

Another important object of this invention is the provision of such a device which may be readily powered by means of the power normally utilized in driving the drill or jack hammer, or the like.

Other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully described hereinafter and disclosed in the accompanying drawings wherein there is shown a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a top plan view of one form of device,

closing the device as viewedfrom the opposite side, the cover plate being removed, and

Figure 4 is a sectional view taken substantially on the line 44 of Figure 1.

Like reference numerals refer to like parts throughout the several views of the drawings.

Having reference now to the drawings, there is generally indicated at ill a cylindrical casing,

open at its extremities and provided with flanges ll "and t2, the openings bein closed by cover plates flanges as by bolts and 'nuts l5 and It passed "through suitable registering apertures in the i3 and M secured to their respective flanges and plates. Sealing gaskets l and'l8 'areinterposed between flange ii and plate [3,

and flange l2 and plate M, respectively.

Centrally-disposed in cylindrical body I0 is a central partition 19 dividing the body into'two equal chambers, and provided with a centrally positioned bore, within which is positioned a sleeve 20 journaled in roller bearings 2|. Suitable sealing rings 22 of felt or the like are positioned exteriorly of the bearings 2| and caps 23 serve to hold the bearings in position in their recesses in partition l9.

Positioned in sleeve 20 for rotation therewith is a shaft or axle 25 threaded at its extremities as at 26 and 21, respectively, and having mounted on the extremities thereof rotors 28 and 29, Rotors 2B and 29 are secured in position, as by sleeves 30 and 3|, respectively, held in position by nuts 32 and 33 engaging respectively the threaded extremities 26 and 21.

As best shown in Figures 2 and 3, each of rotors 28 and 29 is provided with a plurality of blades 34 and 35, respectively, each having an arcuate section adjacent the hub and terminating in a relatively straight blade portion. The rotors are oppositely arranged, in such manner that their respective arcuate portions are reversed with respect to each other, for a purpose to be more fully pointed out hereinafter.

From the foregoing it will now be seen that the rotors are mounted on a common axle, and secured in relatively tight related assembly by the nuts 32 and 33, in such manner that rotation of one from a source of power is transmitted to the other, in such manner that the rotors rotate at equal speed.

The chamber containing the rotor 28 between partition l9 and cover plate It is provided with a peripheral inlet 40 and a centrally disposed outlet 42, while the chamber containing rotor 29 is similarly provided with a peripheral inlet 4! and outlet 43, in the center of cover plate 13.

escape for the compressed air admitted through inlet 4| and is open to the atmosphere.

From the foregoing it will be seen that as compressed air enters the inlet 4| it drives the rotor 29 in the direction indicated by the arrows in Figure 2, and exhausts to the atmosphere through the port or outlet 43. This operation through the shaft drives rotor 28 in the direction indicated by the arrows in Figure 3. Due to the configuration of the blades as, air, and correspondingly dust from the point adjacent the hole being drilled, is sucked in through the inlet 49, and discharged through outlet duct 42 into the receptacle previously mentioned.

Thus, it will be seen that the device of the instant invention serves efiectively to draw the dust from its source adjacent the hole being drilled to confine the same in a suitable receptacle,

and preclude its escape into the atmosphere where it might be breathed into the lungs of the worker.

Now, from the foregoing, it will also be seen that there is herein provided a device which is sturdy and durable in construction, reliable and efficient in operation, and relatively inexpensive and simple to construct and manufacture, which 35 1,657,707

is powered by a normally adjacent source of power, and which accomplishes all of the objects of this invention including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim;

A combined fluid pressure motor and pump comprising, a cylindrical casing having detachable end covers, a diametrical partition dividing said casing into axially aligned, cylindrical, mo-

tor and pump chambers, fluid inlet means dispose peripherally in each chamber, fluid outlet means disposed axiall in each cover, axially aligned, spaced anti-friction bearing means disposed-in the partition in each chamber, sealing and re- .taining means enclosing each bearing means, a rotatable sleeve disposed centrally of said partition and of said bearing means, a shaft extending through and secured tosaid sleeve, a rotor in each chamber secured to an end of said shaft and means for supplying a motive fluid to one of said chambers to the rotor therein, for driving the other rotor as a pump.
